Biography


Hamed was born in Tehran, Iran and did his BSc. in Electrical Engineering (Major in Telecommunications) at K. N. Toosi University of Technology, Tehran, Iran. He received his MSc. in Electrical Engineering (Major in Electromagnetic Fields & Waves) from AmirKabir University of Technology with honors. In 1998, he joined the Department of Electrical & Computer (E&CE) at the University of Waterloo and obtained his PhD with distinction on December 2001. His PhD thesis investigated the optical-microwave interaction in superconducting transmission lines for optoelectronic applications under the supervision of Prof. S.K. Chaudhuri and Prof. S. Safavi-Naeini. After his PhD, he spent 10 months as a postdoctoral fellow in Department of  of E&CE, focusing on superconducting single photon detectors and THz photonic devices and then moved to Institute for Quantum Computing (IQC) as a Research Assistant Professor where he established Integrated Quantum Optoelectronics Lab (IQOL). He becomes an Assistant Professor at Department of E&CE in 2005, cross-appointed with the Institute for Quantum Computing (IQC) and Department of Physics & Astronomy at University of Waterloo. He was promoted with tenure to the rank of Associate Professor in 2010. In 2012, he has spent his sabbatical at Harvard School of Engineering and Applied Sciences, mainly collaborating with Prof. Marko Loncar. He offered graduate courses in Quantum Electronics & Photonics and Modern Optics in applied physics program and Applied Quantum Mechanics for Undergrad students at Harvard University. He has held a visiting associate professor position at Harvard University till end of 2013. He is leading IQOL as the first engineering-based laboratory in Institute for Quantum Computing (IQC). IQOL main focus is on the development of superconducting-based photonic quantum devices, especially superconducting single-photon detectors, sources and waveguides at Infra Red wavelengths.
